Since a long time I have possessed this M1 airborne helmet. It belonged to an unit which was garrisoned in the "Rheinkaserne" nearby the river Rhine in Wiesbaden-Biebrich in the 50s/60s(?) and the helmet rested in Germany. May I ask you if there is a way to date the helmet please? Maybe produced 1944/45 with rear seam and clasps of the chinstraps added latter or a post war procuction (Korean era)? By the way it's interessting that the clasps were fixed originaly with light green tape.
Maybe someone knows about an US airborne unit garrisoned in the "Rheinkaserne" at Wiesbaden-Biebrich?
With best wishes
